<title>SchemaValidate Task</title>
</head>

<body>

<h2><a name="schemavalidate">SchemaValidate</a></h2>
<h3>Description</h3>

<p>This task validates XML files described by an XML Schema.
The task extends the XmlValidate task with XSD-specific features.</p>
<ol>
<li>The parser is created validating and namespace aware
</li>
<li>Validation is turned on.</li>
<li>and Schema validation is turned on.</li>
<li>Any default schema supplied is used as the no-namespace schema
<li>All nested schema declarations are turned into the list of namespace-url
bindings for schema lookup.
</ol>

Note that nested catalogs are still used for lookup of the URLs given as the
sources of schema documents, so you can still delegate lookup to a catalog, you
just need to list all schema URIs and their URL equivalents.

<p>This task supports the use of nested
<li><a href="../CoreTypes/xmlcatalog.html"><tt>&lt;xmlcatalog&gt;</tt></a> elements</li>
<li> <tt>&lt;schema&gt;</tt> elements, that bind a namespace URI to a URL or a
local filename.
<li><tt>&lt;dtd&gt;</tt> elements which are used to resolve DTDs and entities.</li>
<li><tt>&lt;attribute&gt;</tt> elements which are used to set features on the parser.
These can be any number of
<a href="http://www.saxproject.org/apidoc/org/xml/sax/package-summary.html#package_description"><tt>http://xml.org/sax/features/</tt></a>
or other features that your parser may support.</li>
<li><tt>&lt;property&gt;</tt> elements, containing string properties
</p>

<p>
The task only supports SAX2 or later parsers: it is an error to specify a SAX1
parser.
